In one embodiment, the present invention provides a modular vacuum system comprising: a first canister having a first capacity configured to store debris; a second canister having a second capacity greater than the first capacity configured to store debris; a first power head; and a second powerhead. The first powerhead may be coupled to either the first canister or the second canister. The first powerhead may be operable at a first voltage to generate a first suction airflow, and the first powerhead may be coupled to the first canister such that the first canister receives the first suction airflow. The first canister stores debris separated from the first suction airstream. The first powerhead may be coupled to the second canister such that the second canister receives the first suction airflow. The second canister stores debris separated from the first suction airstream. The second powerhead may be coupled to either the first canister or the second canister. The second powerhead may be operable at a second voltage greater than the first voltage to generate a second suction airflow, and the second powerhead may be coupled to the first canister such that the first canister receives the second suction airflow. The first canister stores debris separated from the second suction airstream. The second powerhead may be coupled to the second canister such that the second canister receives the second suction airflow. The second canister stores debris separated from the second suction airstream.
In another embodiment, the present invention provides a modular vacuum system comprising: a first canister having a first capacity configured to store debris; a second canister having a second capacity greater than the first capacity configured to store debris; and a powerhead coupleable to either of the first canister or the second canister. The powerhead is operable to generate a suction airflow.

Detailed Description
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.
Fig. 1-5 illustrate a modular vacuum system 10. The modular vacuum system 10 includes a first powerhead 12, a second powerhead 14, a first canister 16, a second canister 17, a third canister 18, and a base 20. The powerheads 12, 14 may be connected to the canisters 16, 17, 18 by using a latch 19, and the canisters 16, 17, 18 may be connected to a base 20. The latch 19 may be actuated to lock the powerheads 12, 14 to the canisters 16, 17, 18 or to release from the canisters 16, 17, 18. The powerheads 12, 14 have different performance levels and the canisters 16, 17, 18 have different capacities. Thus, the user may select the capabilities of the powerhead, the size of the canister, and the base 20 to be modular and custom designed to meet the user's needs.
Figure 5 shows the first powerhead 12 and the second powerhead 14. The first powerhead 12 has a first performance level and includes a first fan 21 and a first motor 22. The second powerhead 14 has a second performance level that generally exceeds the first performance level and includes a second fan 23 and a second motor 24. The first performance level has a first voltage and the second performance level has a second voltage greater than the first voltage. The first voltage is provided by an 18 volt lithium ion battery 25. The second voltage is provided by two 18 volt lithium ion batteries 25 which form a 36 volt system. In other embodiments, different battery voltages may be used. In another embodiment, the powerheads 12, 14 include an AC power input 26 to charge an 18 volt lithium ion battery 25 and/or to power the powerheads 12, 14 when the 18 volt lithium ion battery 25 is not in use. In yet another embodiment, the powerheads 12, 14 may be powered solely by the AC power input 26. The powerheads 12, 14 may include horizontal filters. The filter is interchangeable for different uses: wet, dust, HEPA, etc. In one embodiment, the filter includes a visual indicator on one side of the filter so that the user can know what type of filter (e.g., wet, dust, HEPA, etc.) is installed.
As shown in fig. 4 and 5, the cans 16, 17, 18 have a plurality of can sizes. In the illustrated embodiment, the first tank 16 has a capacity of two gallons to six gallons. The second tank 17 has a capacity of seven gallons to sixteen gallons. In other embodiments, the tanks 16, 17, 18 may have a capacity of from two gallons to twenty gallons. The tanks 16, 17, 18 have an open upper end 27 and a closed lower end 28. Fig. 5 shows that the first tank 16 has a first height 30 measured from the open upper end 27 to the closed lower end 28. The second tank 17 has a second height 31 and the third tank 18 has a third height 32. The open upper end 27 is shaped with a first polygonal cross-section 33 and the closed lower end 28 is shaped with a second polygonal cross-section 34. The size and shape of the open upper end 27 and the closed lower end 28 are consistent from one tank 16, 17, 18 to the next. Thus, in the illustrated embodiment, the capacity of each tank varies with the height 30, 31, 32 of the tanks 16, 17, 18. The canisters 16, 17, 18 may be connected to the powerheads 12, 14 at an open upper end 27, and the canisters 16, 17, 18 may be connected to the base 20 at a closed lower end 28.
Referring to fig. 1 and 2, the base 20 includes a handle 38, a release 40, wheels 41 and a brake 42. The release 40 is used to unlock the canisters 16, 17, 18 from the base 20 (e.g., for emptying or for replacing the canisters or the base). In the illustrated embodiment, the handle 38 is an adjustable handle connected to the base 20 for moving the canisters 16, 17, 18 when the canisters 16, 17, 18 are attached to the base 20. The release 40 is a release lever that is actuated to remove the canisters 16, 17, 18 from the base 20. In one embodiment, release 40 may be a foot-actuated release lever. In the illustrated embodiment, the brake 42 prevents the base 20 from moving by locking the at least one wheel 41.
Referring to fig. 3-5, the canisters 16, 17, 18 may be free standing without a base 20. That is, the canisters 16, 17, 18 may be placed on the floor and the modular vacuum system 10 may be used without the base 20. In some embodiments, the canisters 16, 17, 18 may include an integral handle for emptying.
In the embodiment shown in FIG. 2, the modular vacuum system 10 includes an inlet 44 attached to the first powerhead 12. A hose 48 is removably coupled to the inlet 44. During operation of the modular vacuum system 10, the first motor 22 is operated at a first voltage to generate a first suction airflow through the inlet 44. The first suction airstream collects debris passing through the inlet 44. Debris is separated from the first suction airstream and stored in the canisters 16, 17, 18. In one embodiment, the inlet 44 may be attached to the second powerhead 14. In this embodiment, the second motor 24 generates a second suction airstream through the inlet 44, wherein the second suction airstream collects debris and the debris is separated from the second suction airstream and deposited in the canister 16, 17, 18. Fig. 5 illustrates the modularity of the modular vacuum system 10, showing the canisters 16, 17, 18 coupled to the powerheads 12, 14 such that the canisters 16, 17, 18 may receive the first or second suction flow generated by the powerheads 12, 14. In yet another embodiment, the inlet 44 may be attached to the tanks 16, 17, 18.
